Hmm, interesting. My Penguinized/Panda'd site is seeing some big improvements... but not on the keyphrases I used to do well on. Those are still down in the cellar as they have been since Penguin (and I'm guessing that's why a Panda update didn't help them). The pages benefiting most from this have not had their content changed (other than replacing stock photos with originals), but they have enjoyed a storm of social media sharing in the past few months.
